The Dayton Agreement rests on the principle of establishing a self-sustaining system that respects the multinational and multiconfessional structure of the population of Bosnia and Herzegovina, composed of entities with independent constitutive, legislative, executive and judicial functions. The organisation and functioning of the constitutionally-determined institutions of power in BiH is based on the constituent nature of the nations, enclosed in amendments to the entity constitutions made after the 2000 Decision of the Constitutional Court on the Constituency of Peoples, which regulate representation and the manner of the protection of the interests of the peoples. This article proceeds from the point that vital discussion on constitutional regulation is leading to a marginalisation of the discussion on harmonising domestic legislation with the EU acquis, conditio sine qua non in terms of fulfilling the requirements of the Stabilisation and Accession Agreement, not least in the area of labour law, and gaining admission to the EU. Above all, society is only changed through reform in which - panta rei - everything flows.
